This patchset adds proper support for sliced reads of partitions
containing range tombstones.
Given the SSTables 3.x repesentation of range tombstones by separate
start and end markers, we refer to the index for the information about
the currently opened range tombstone, if any, when skipping to the next
promoted index block.
Note that for this we have to take the promoted index block immediately
preceding the one we are jumping to.
Tests: unit {release}
